RFOG ONU FTTH Optical Receiver
The FTTH optial receiver return path adopts burst mode RFOG (turn on the laser when have return signal), which greatly reduced the noise collection.
INFORMATION
Performance Characteristics
Excellent AGC characteristic, when the input optical power range is -7～+2dBm, the output level, CTB and CSO basically unchanged.
Professional RF attenuator circuit, with good attenuation linear and high precision.
GaAs amplifier device, with good index, low distortion and high reliability.
The return path control adopts burst mode, which greatly reduced the noise collection.
The shell adopts aluminum die casting, the heat dissipation effect is good and the appearance is exquisite.
The power supply mode is external DC +12V.
